Further, a driver's seat 10 and a tandem seat 11 are continuously provided from substantially the center of the vehicle to the rear.

As a vehicle body cover, the front cowling 12 covers the front portion of the motorcycle 1 and a headlight 13 is provided.
The side cowling 14 is provided so as to continue to the front cowling 12 and covers the lower side surface of the motorcycle 1.
The recowling 15 covers the lower part of the seats 10 and 11 at the rear part of the motorcycle 1 and is provided with a taillight 16.

  A wind screen 17 is disposed above the front cowling 12. Meters are disposed above the front cowling 12 and behind the wind screen 17, and the periphery thereof is covered with an inner cover 18. The inner cover 18 includes a dash panel portion 19 and a box wall portion 20. In the dash panel portion 19, as shown in FIG. 5A, an opening 21 through which the top bridge 4 is exposed is formed. The box wall portion 20 is formed with an opening of a glove box, and a lid member 22 that closes the opening is provided.

  The center tunnel 23 is connected to the lower end of the inner cover 18 and extends rearward. The inner wall 24 is provided below the center tunnel 23 so as to continue to the center tunnel 23. The floor board 25 functions as an occupant's footrest and is provided on both sides of the inner wall 24 so as to be continuous with the inner wall 24.

  Here, as shown in FIGS. 2 and 5A, a handle cover 26 is disposed above the dash panel portion 19 of the inner cover 18 to cover the opening 21 where the top bridge 4 is exposed. As shown in FIG. 3, the handle cover 26 includes a front cover 26a and a rear cover 26b. A claw-shaped fitting portion and a pin-shaped clip 33 (only one place is shown in FIG.

(Second Embodiment)
In the second embodiment, an example of a cruiser type (also called American type) motorcycle will be described. FIG. 6 is a side view of the motorcycle 100 according to the second embodiment. FIG. 7 and FIG. 8 are schematic views showing the mounting structure of the accelerator position sensor in the second embodiment.

  The steering stem is pivotally supported by the steering head pipe 102 so that the left and right front forks 103 (telescopic forks) are steered left and right. A handlebar 104 is fixed to the steering stem, and grips 105 (throttle grips at the right end) are attached to both ends of the handlebar 104 in the vehicle width direction. A front wheel 106 is rotatably supported at the lower portion of the front fork 103, and a front fender 107 is disposed above the front wheel 106.

A front end portion of the down tube 101 and a front end portion of the tank rail 111 are coupled to the steering head pipe 102.
The pair of left and right down tubes 101 branch left and right from the steering head pipe 102 and extend obliquely downward (hang down the front side of an engine unit 114 described later), then bend and extend substantially horizontally toward the rear of the vehicle. . A swing arm 108 is swingably positioned at the rear of the down tube 101, a rear wheel 109 is rotatably supported at the rear end of the swing arm 108, and a rear fender 110 is disposed above the swing wheel 108.

  The pair of left and right tank rails 111 branch left and right from the steering head pipe 102 and extend substantially rearward of the vehicle. The tank rail 111 and a seat rail (not shown) connected to the tank rail 111 are mounted with a fuel tank 112 and a seat 113 that extends to above the rear fender 110.

An engine unit 114 is mounted between the down tube 101 and the tank rail 111. In the present embodiment, the engine unit 114 is a water-cooled V-type two-cylinder engine, and includes cylinders 114F and 114R that open in a V-shape before and after.
The down tube 101 and the tank rail 111 are connected by a plurality of cross members on the left and right, respectively, and are connected by a rear arm bracket and a seat pillar in the vertical direction, thereby constituting the entire body frame of the motorcycle 100. The

  In this type of motorcycle, on one side of the vehicle, an air box is disposed between the front and rear cylinders 114F and 114R that are opened in a V shape, and an air cleaner box cover that covers the air cleaner box is disposed. As shown in FIG. 6, on the opposite side of the vehicle, a so-called pair cover 115 is disposed so as to correspond to the air cleaner box cover.

  As shown in FIGS. 7 and 8, a support member 116 is provided so as to be installed between the front and rear cylinders 114F and 114R. One end of the support member 116 is fixed to the side surface of the front cylinder 114F by a bolt 117, and the other end portion is fixed to the side surface of the rear cylinder 114R by a bolt 118. A support portion 116a is formed by bending the outer end portion of the support member 116 further to the outside in the vehicle width direction than the fixing portion to the cylinders 114F and 114R. Further, a boss part 119 is provided on the inner surface of the pair cover 115, the boss part 119 comes into contact with the support part 116 a of the support member 116, and the pair cover 115 is fixed by the bolt 120.

  An accelerator position sensor 121 is attached to the center of the support member 116. Thus, since the accelerator position sensor 121 is attached using the existing support member 116 for fixing the pair cover 115, it is not necessary to provide a dedicated part, and the cost can be reduced. The accelerator position sensor 121 is fixed to the support member 116 by a bolt 122, and is fixed in a floating state by a rubber mount 123 at that time. The accelerator position sensor 121 detects the amount of operation of a throttle grip provided at the right end of the handle bar 104 via a throttle cable (not shown).

As described above, since the accelerator position sensor 121 is covered with the existing pair cover 115, it is excellent in waterproofness and dustproofness without impairing the appearance. Moreover, if the pair cover 115 is removed, the accelerator position sensor 121 can be easily accessed, and the maintainability is excellent.
In addition, since the accelerator position sensor 121 is installed in a portion not related to the steering mechanism, the operability is not affected.

In the present embodiment, the accelerator position sensor 121 is attached to the support member 116, but the accelerator position sensor 121 may be attached to the inner surface of the pair cover 115. In this case, for example, a boss portion may be appropriately provided on the inner surface of the pair cover 115, and the accelerator position sensor 121 may be fixed to the boss portion with a bolt.
Further, although the accelerator position sensor 121 is disposed inside the pair cover 115, the accelerator position sensor may be disposed inside the air cleaner box cover on the opposite side of the vehicle.

As mentioned above, although this invention was demonstrated with various embodiment, it is not limited only to these embodiment, A change etc. are possible within the scope of the present invention.
In the above embodiment, the accelerator position sensor mounting structure in a motorcycle has been described. However, the application destination of the present invention is not limited to a motorcycle, and may be a three-wheeled vehicle or a four-wheeled vehicle.
